HIGH HONOR ROLL

JARED SULLINGER: The 14.5 points in less than 25 minutes a game is nice, but within that he's shooting better than 58 percent on 3s. His low-post game, coupled with shooting the ball so well from deep range, will make him a tough cover this season. GRADE: A

EVAN TURNER: Versatility has been a strength of his game for years, and it certainly has benefited the Celtics thus far. His numbers -- 11.8 points, 6 rebounds and 4.3 assists per game -- speak to how the 6-foot-6 wing has the potential to rack up triple-doubles at a Rajon Rondo-like rate. GRADE: A

MERIT ROLL

MARCUS SMART: His shooting needs some work, but the defensive impact he brings is undeniable. His physical strength and lateral quickness have been tremendous so far, and will only get better in time. GRADE: B+

BRANDON BASS: After spending most of his time in Boston as a starter, Bass has shown the ability to impact the game as a reserve, too. GRADE: B+

KELLY OLYNYK: Strength is still an issue for him when playing center, but he has the ability to affect the game in multiple ways. GRADE: B+

HONORABLE MENTION

TYLER ZELLER:After a slow start, Zeller is starting to contribute in ways that will not only help the Celtics but also secure a spot in the regular playing rotation. GRADE: C+

JAMES YOUNG: The 19-year-old wing has been the ultimate tease on the floor. He misses all of Summer League, shows a nice, well-rounded game in the preseason and now he's out again. So far, staying healthly appears to be his biggest hurdle. GRADE: C+

GERALD WALLACE: His minutes have been limited throughout the preseason, a good precursor for how things will be when the season starts. Grade: C

JOEL ANTHONY: Even with a clear opening at center, look for Anthony to spend most of his time on the bench. His offensive game has never been very good, and defensively he doesn't impact the game the way he did with the Miami Heat. GRADE: C-

NEEDS IMPROVEMENT

DWIGHT POWELL: After spending most of his career in the post at Stanford, the Celtics are converting the 6-foot-11, 240-pound rookie into a small forward. His length is a major asset in the position, but his footwork and timing aren't anywhere close to where they need to be for him to be effective. GRADE: C-

PASSING

TIM FRAZIER, ERIK MURPHY, RODNEY McGRUDER and CHRISTIAN WATFORD: They have no realistic shot of making this team, with most likely playing for the Celtics' Development League team in Portland, Maine, or taking their talents overseas. GRADE: N/A

NO GRADE

RAJON RONDO, VITOR FAVERANI and JEFF GREEN: All three have not played a single game in the preseason because of injury, with Green being the only one who will see action before the preseason ends. GRADE: N/A
